Mobile Application Part (MAP) is an SS7 protocol used by various elements in GSM, UMTS, and GPRS mobile “core” networks to provide services to mobile phone users.

GL Communications Inc. announced today the release of its latest GSM & UMTS MAP Emulation software.

Speaking to reporters, Mr.Karthik Ramalingam Product Development Manager said, “Mobile Application Part (MAP) is an SS7 protocol used by various elements in GSM, UMTS, and GPRS mobile “core” networks to provide services to mobile phone users. In a recent article, it has been described as one of the real “technological triumphs of GSM”. Common services provided by MAP are “location tracking”, “roaming”, “subscription information”, “short message service”, and many more.

Traditionally SS7 is carried by TDM (T1 and E1) circuits, but recently with the popularity of the internet and IP, a special IP protocol called SIGTRAN is rapidly gaining acceptance.”

He added, “GL’s MAPS™ (Message Automation and Protocol Simulation) product line is used to emulate all the MAP interfaces provided in the below picture viz., B MSC-VLR, C MSC-HLR, D VLR-HLR and other interfaces – for both TDM and IP.

MAPS™ is an advanced and versatile protocol simulator/tester that can simulate a variety of protocols encountered in the telecom space, including for example ISDN, CAS, SS7, and many more. Now it also supports all the GSM and UMTS MAP interfaces. In addition to supporting the MAP network elements connected by the interfaces listed, also supported are error tracking, regression testing, conformance testing, load testing and call generation. It can run pre-defined test scenarios against test objects in a controlled & deterministic manner.”

Mr. Ramalingam further added, “MAPS™ MAP Emulator supports powerful utilities like Message Editor, Script Editor, and Profile Editor which allow new scenarios to be created or existing scenarios to be modified using MAP messages and parameters.”

Important Features:

·MAP protocol simulation over TDM (E1/T1) and IP
·Emulator can be configured as MSC (VLR), HLR, GMSC, EIR, AuC, SMSC, SGSN and GGSN entities and emulate the respective interfaces
·User-friendly GUI for configuring the MAP signaling links
·Access to all MTP3, SCCP, and MAP R4 protocol fields such as TMSI, IMSI, MCC, MNC, MSIN, CCBS and more
·Ready scripts for monitoring other end, set reporting state for the requested service, report an event or call outcome, report remote subscriber status procedures
·Logging of all messages in real-time
·Save and load configurations
·Supported on Windows® XP (or higher) operating systems

About GL Communications Inc.,

Founded in 1986, GL Communications Inc. is a leading supplier of test, monitoring, and analysis equipment for TDM, Wireless, IP and VoIP networks. Unlike conventional test equipment, GL's test platforms provide visualization, capture, storage, and convenient features like portability, remotability, and scripting.

GL’s TDM Analysis & Emulation line of products includes T1, E1, T3, E3, OC-3, OC-12, STM-1, STM-4, analog four-wire, and analog two-wire interface cards, external portable pods, and complete system solutions. Capabilities include voiceband traffic analysis and emulation across all traffic types (voice, digits, tones, fax, modem), all protocols (ISDN, SS7, GR-303, Frame Relay, HDLC, V5.X, ATM, GSM, GPRS, LTE, etc.), and with capacities up to thousands of channels. Our newest products provide astonishing capacity and capture capability up to and including gigabit speeds.

GL’s VoIP and IP products generate / analyze thousands of calls and traffic simultaneously with traffic types such as frames, packets, voice files, digits, video, tones, noise, and fax. Almost all codecs are supported including G.711, G.729, AMR, EVRC-A,B,C, GSM, iSAC, and many more. Additional features include visual analysis, real-time listening, and recording. The product line also includes Ethernet / IP Testing capability that simulates and checks frame transport and throughput parameters of Ethernet and IP networks, including delay, errors and other impairments.

GL's Voice Quality Testing (VQT) product line complements all of GL's products. Using ITU-standard algorithms (PAMS, PSQM, and PESQ), GL's VQT provides a widely accepted solution for assessing voice quality in the telecom industry. Voice Quality Testing across multiple networks (T1, E1, T3, E3, OC-3, OC-12, VoIP, Wireless, and Landline) are all available.

GL’s Wireless Products perform protocol analysis and voice quality assessment on GSM, CDMA, UMTS, and LTE networks. Connections can be made to any wireless phone with automated call control, GPS mapping and real-time signal measurements.

GL’s Echo Canceller testing solutions provide the broadest range of simulation and analysis, including line and acoustic echo. GL’s compliance testing per G.168. G.167, and P.340 across TDM, IP, VoIP and Wireless networks is widely accepted in the industry.

GL’s wireless VQT solutions help assessing impairments to voice quality such as poor mobile phone quality, voice compression and decompression algorithms, delay, loss and gain in speech levels, noise, acoustic and landline echo, and other distortions are easily assessed and accurately measured.

GL’s handheld data testers can test a wide variety of communications facilities and equipment including T1, fractional T1, E1, fractional E1, T3 and E3 modems, multiplexers, CSU, DSUs, T1 CSUs, DTUs, NTUs and TIUs and more. The testers provide convenience, economy, and portability for almost any interface, including RS232, RS-422, RS-530, X.21, T1, E1, T3, E3, and many others.

GL’s Network Surveillance and Monitoring products include Probes for TDM, IP, VoIP, ATM, and Wireless networks. An open standards based approach provides a scalable, feature rich, real-time access to network characteristics. Centralized or distributed access, efficient transport and database loading allow compatibility with 3rd party and standards based monitoring systems.
